  I counted 52 wires x 52 wires in the top plane
 I counted either 20 or 19 total planes 
I count 50 x 40, and 20 planes.  I think you need glasses, Jim :-)
  In looking at the photo, it appears that there are 2
of those wires thru
 each core, so this is 26*26*20 or 13520 bits total 
I only see one X and one Y plus the sense wire through each core (and
the cores are laid out like that), so I make it 2000 x 20 = 40000.
  The connector marked X has 40 conductors.  I would
assume there is also
 a Y connector, and maybe fewer sense lines?   
5.jpg shows 50 Y connections.
  maybe only 1 sense line per plane? 
That's normal.
